DESCRIPTION
One boom is available on the crane; a five section, full
power, sequenced and synchronized, 42 to 159.3 ft (12.8 to
48.5 m) boom. The boom assembly utilizes a mega form
design. The five section boom utilizes two sequenced
telescope cylinders for telescoping and retracting of the
boom plus cable synchronization for the extension and
retraction of the fly section. Boom lift is provided by a single
lift cylinder and boom elevation is from -3 degrees to +78
degrees.
Lattice Extension
The 11 to 18 m (36 to 59 ft) offsettable bifold lattice
swingaway extension stows alongside the base boom
section. Offsets are 0°, 20°, and 40°.
Optional Lattice Extension
36 to 59 ft (11 to 18 m) hydraulically offsettable bifold lattice
swingaway extension stows alongside the base boom
section. Offsets are from 0° to 40°.
Optional Lattice Extension Inserts
The 26 ft (8 m) non-stowable lattice extension inserts install
between the boom nose and bifold extension. A standard
auxiliary boom nose (rooster sheave) is available for the
boom to simplify single part cable usage. The rooster sheave
is installed on the main boom nose and is secured by pins
that pass through the rooster sheave and main boom nose.
